Supercharger

  1. 1. A SEMINAR REPORT ON SUPERCHARGER SUBMITTED TO:- SUBMITTED BY:- DR. CHITRANJAN AGARWAL PRAKASH CHAND KUMAWAT
  2. 2. INTRODUCTION  A supercharger is an air compressor used for forced induction of an internal combustion engine.  The higher concentration of oxygen provided by a supercharger is matched with a larger amount of fuel from the fuel injectors thus boosting the power of the engine.
  3. 3. Principle of working  More fuel + More air = Bigger explosion = Greater horsepower  But we cannot simply pump more fuel into the engine. chemically correct mixture – (14 : 1 :: air : fuel) – is essential for an engine to operate perfectly.  The  Thus superchargers provides more air by compressing air above atmospheric pressure , hence providing more fuel into the charge & would make for a more powerful explosion .  Thus: Increased Power , Torque and Speed is achieved.
  4. 4. SUPERCHARGER TYPES  1. BASICLY THREE MAIN TYPES OF THE SUPERCHARGERS:- Roots Types 2. Centrifugal Type 3. Screw Type
  5. 5. Roots supercharger  It consists two cylindrically shaped lobes in opposite direction in a common housing.  Air enters the space in between the rotor lobes at inlet and is carried around the rotor to discharge port.
  6. 6. A standard engine with the addition of a supercharger
  7. 7. Centrifugal Superchargers  It consists an impeller which is rotates in clock-wise direction.  The air enters the hub of the impeller axially and is turned radially by radial vanes.  The air leaves the impeller at high speed, but low pressure.  A diffuser converts the high-speed , lowpressure air to low-speed , high-pressure air.
  8. 8. Twin-Screw Supercharger  It contains a set of worm gears.  Air enters in supercharger through the top rear and it’s compressed between the rotors.  The male rotor is rotates in clock-wise while female rotor rotates counter clock-wise and compressed air between them.  Once the air is screwed and compressed the full length of the rotors it remains in compressed state between the rotors until the engine demands the boosted air.
  9. 9. Drives used in supercharger Mechanical: Belt  Gear drive  Chain drive. Other: Electric motor.
  10. 10. Advantages of Supercharger  Increased power  No lag – Consistent power delivery  Generally better throttle response   No Special Procedures or extra maintenance Easier to install than turbochargers
  11. 11. Disadvantages of Supercharger   Consumes a lot of power from the engine (therefore not very efficient) Increases the strain on the engine  Expensive  Noise
